Converts a frequency matrix to a weight matrix. Weight matrices are used for probabilistic recognition of transcription factor binding sites.
Parameters in GUI
| Parameter | Description | Default value |
|---|---|---|
| Matrix type (required) | Dinucleic matrices are more detailed, while mononucleic one are more useful for small input data sets. | Mononucleic |
| Weight algorithm | Different weight algorithms uses different functions to build weight matrices. It allows us to get better precision on different data sets. Log-odds, NLG and Match algorithms are sensitive to input matrices with zero values, so some of them may not work on those matrices. | Berg and Von Hippel |
